SODIUM THIOSULPHATE AND HYDROCHLORIC ACID CHEMISTRY COURSEWORK

My Error bar graph shows a negative correlation. This ensures that the solution is completely opaque when I stop the timer. Investigating the rates of reaction of Sodium thiosulphate and hydrochloric acid – Investigating the rates of reaction of Sodium thiosulphate and hydrochloric gcse Using my preliminary experiments I decided on using the following apparatus: Sorry, but copying text is forbidden on this website. These are circled on my graphs. The page you are looking for might have been removed, had its name changed, or is temporarily unavailable.

There is five factors which affect the rate of a reaction, according to the collision theory of reacting particles: Burning and explosions are very fast reactions: My data has proven to be reliable and I am therefore happy to use it to make a justifiable conclusion that concentration does have an effect on rate of reaction. Papers] Gcse Essays words 3. Heavier particles move more slowly than light ones at a given temperature. I will discuss these further in my evaluation. Investigating the rates of reaction of Sodium thiosulphate and hydrochloric acid – Investigating the rates of reaction of Sodium thiosulphate and hydrochloric gcse Using my preliminary experiments I decided on using the following apparatus:

(DOC) GCSE CHEMISTRY RATES OF REACTION COURSEWORK | Anjelina Qureshi –

The bars of 1M and 2M overlap and this shows that there is no real difference. If I do a further investigation, I will try to minimise the number of mistakes that I make. The reaction gcse sodium reaction and HCL Length: This makes sure that my experiment runs smoothly. The rate of reaction between sodium thiosulfate and hydrochloric acid send By clicking “Send”, you agree to our terms of service and privacy policy.

Background Research Chemical reactions are to do with changing the materials that form the base of your experiment. Use of rate of reaction in industry The chemical industry makes medicine and many other substances such as; Limestone – this is used for building Sulphuric acid — used to make other substances Ammonia – used to make fertilisers.

This increases the likelihood of reactants colliding properly and so increases the rate of the chemical reaction.

My Error bar graph shows a negative correlation. I made sure that I had everything before I started. Free Essays words 3. I hydrovhloric that as the concentration of the Sodium Thiosulphate doubles, the rate of the ccoursework will double.

Investigating the rates of reaction of Sodium thiosulphate and hydrochloric acid – Investigating the rates of reaction of Sodium thiosulphate and hydrochloric gcse Using my preliminary experiments I decided on using the following apparatus: The enthalpy change is the amount of heat absorbed or released when a chemical reaction occurs at a constant pressure.

For example, when my concentration was 1M the average reaction chemjstry was seconds, and then when the concentration was 5M the average reaction time was seconds. Oops, we could not find the requested page.

I will be timing and watching: This could have happened because of calculation errors, human errors, recording errors or a fault with the equipment that we used. The page you are looking for might have been removed, had its name changed, or is temporarily unavailable.

To do this I would make sure that: These two acids hyrdochloric well with the right materials. I tied my hair back, tucked in my tie and pushed all stools and bags under the desk where there is no risk of anyone tripping. Sorry, but copying text is forbidden on this website! There is one outlier in 2M concentration. Click chemistry button above to view the complete essay, speech, term paper, or research paper.

For every one M increase, the rate for reaction increases by 2. I am investigating the different factors which may speed up chemical reactions. I stood up to allow more space for others to walk by between the rooms. I also made sure that any clothing or long jewellery was clear and out of our way as clothing can also get caught.

We must produce a piece of coursework investigating the rates of reaction, and the effect different changes have on them. The size of the error bars is quite small so I think I can say that my data is quite accurate except for the 2M result which is quite hydrocnloric long error bar.

The rate of reaction between sodium thiosulfate and hydrochloric acid Essay

I have used reliable resources to research this information and it all confirms my conclusion. And supports my conclusion. The conical flask and all other equipment must be clean as any impurities may contaminate my experiment.

These reactions only happen if the reacting hydrochlori collide properly.
